Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556614, here are decompositions:

113 + 31556501 = 31556614
137 + 31556477 = 31556614
191 + 31556423 = 31556614
197 + 31556417 = 31556614
233 + 31556381 = 31556614
311 + 31556303 = 31556614
647 + 31555967 = 31556614
743 + 31555871 = 31556614

Showing the first eight; more decompositions exist.
